Meanwhile, Rick Santorum criticized the Obama family's decision to allow the first daughter to travel to Mexico when the State Department has issued travel warnings about the country.

"If the administration is saying that it's not safe to have people down there, then just because you can send 25 Secret Service agents doesn't mean you should do it," Santorum told Glenn Beck on his radio show. "You should set an example. I think that's what presidents do. They set an example."
